ADDRESSING OR LIKE Application filed August 9,

T0 at wit-0171, it may concem:

Be it known that I, Louis MAUnIc-n BARMAN, a citizen of the United States of America, residing at Holborn, London, England, Great Britain, have invented new and useful Improvements in Addressing or like Printing Machines, of which the following is a specification.

This invention relates to improvements in addressing or like printing machines, and has reference to the type of machine where- 'n the stencil cards, or the like are inserted in a hopper or magazine in such a manner that a pusher member acts upon the lowermost stencil card, releases it from the pile, and positions it between the printing rollers.

In machines of this class it is important that means be devised whereby the operator can tell when the last stencil card or the like has been slid by the pusher member to its position for printing.

Hitherto the means for notifying theoperator of this fact has been in the nature of a gong or bell, and such devices have more or less depended upon the alertness of the operator.

It is also known that paper feeding apparatus has been provided with a vertically movable table or support which is raised as successive cards or sheets are fed from the top of a pile to rollers, such apparatus not only maintaining the upper sheet in line with the feeding rollers, but also moving a part of the sheet to posit-ion to be drawn from the top of the pile by engagement with the rollers. A machine for this purpose has a stop motion which operates when the last sheet has been removed.

The present invention has for its object to provide a machine the construction thereof being such that when the last or bottom stencil card has been removed from the hopper or magagine by the pusher member, the machine will be locked against further movement until the presser weight has been removed and another stack of cards, sheets, or stencils has been placed in the magazine.

The device for stopping the action of the machine, in one form, comprises a weight, formed of metal or like substance which normally rests upon the upper surface of a stack or pile of stencil cards placed in the hopper,

and the said weight is provided with a knob for handling purposes and has, moreover, a surface or surfaces thereon in the nature of 51433 .NFFECE.

a lug, or upstanding projection which acts upon one of the walls of the hopper or magazine in such a manner as to prevent movement of the pusher member.

The weighted pressing member placed on the stack becomes means for rendering operative a locking device after the last stencil has been acted upon by the reciprocating pusher member.

Theinvention will now be described more fully by reference to the accompanying drawings illustrating part of a machine shown more fully in my previous application for the United States patent Serial No. 123,092- filed 10th November 1920.

On the drawings z- Fig. 1. shows a plan view with the locking device in operation.

Fig. 2. shows similar parts in elevation.

Fig. 4:. shows an elevational view of a modified form of the locking device.

Fig. 5. shows a plan view of the modified locking device. 1

Fig. 6. shows a further modification.

Fig. 7. shows means whereby a locking device is secured to one of the sidesof the hopper.

Fig. is a detail view which shows a side elevation of the locking device with means for suspending the same.

Fig. 5). showsa side elevation of the looking member turned over and suspended clear of the hopper or magazine.

Referring to figures 1, 2, and 8, the base plate 1 of the machine has secured theretoby means of brackets 2, or the like, slideways or tracks 3.

Secured through the tracks or sideways to the base plate 1 are two standards 4 spaced apart to form between the uprights or standards 4, which bridge the space between the slideways, a hopper or magazine for the stencils.

The slideways or tracks 3 maintain between them a reciprocating pusher member 5 which is operated by a link or bar 6 connected up in any well known manner and movable through appropriate gear contained in the casing 7 said gear being operated by the handle 8. The pusher member 5 is provided with lugs or projections 9 which are below the plane of the plate or pusher member 5, said lugs extending be- 3. is a detail view of the weight lockill) fit)

yond the edge of the plate, so that when the plate is actuated the lugs9 willextend beneath the under surface of the bottom stencil card of a stack, .the edge of the plate contacting with the edge of the card.

Resting upon the pile of stencil cards is the weight locking device, which comprises a metal surface 11 having an upturned edge or projection 12, and a centrally disposed knob 13, and a cut out portion or recess M which registers with a burr or rib 15 formed on one of the side standards 4, see Fig. 1.

Referring to Fig. 2, it will be seen that the hopper is empty that is to say, the reciprocating pusher member has acted upon the last stencil in the magazine and is about to resume its forward movement. When this takes place, the edge 12 of the weight locking member 11 is caught against the surface of the standard 4: and so prevents further movement of the pusher member, and consequently, further rotation of the handle 8 is checked until the weight looking member is removed by means of the knob 18, to replenishthe magazine.

In the modification shown in Figs. 4 and 5 a pair of posts 15 are secured to the slide ways between the standards 4 and the weight locking device 11 is formed with upwardly and outwardly fashioned ears or lugs 16 'perforated as at 17 for passing over the said posts 15.

Fig. 6 shows a further modification in which the weight locking member 11 has depending pro ections 18 which are adapted to register and enter holes drilled in the base 1.

Figs. 7, 8, and 9 show a further modification of the weight locking device wherein one of. the-sides of the hopper consists of a plate having a pair of vertical slots 19 formed therein adapted to receive the hooks v20 formed on the member 11 the said hooks holding the weight locking member when. turned over the top of the standard 4; and suspended outside of the hopper when placing stencil cards therein, as represented in Fig. 9.

Having thus described my invention what I desire to secure by Letters Patent of the United States is as follows 1. In a card or stencil feeding device in which cards or stencils are fed consecutively from the underside of a stack comprising means for. maintaining a vertical stack of cards or stencils, a reciprocatory pusher for engagement with the lower card or stencil of the stack, and a member which normally rests upon the uppermost card or stencil of the stack, the same alining with the pusher when the last card or stencil of the stack has been removed and in the absence of a card or stencil, preventing movement of the pusher.

2. In a card or stencil feeding device wherein cards or stencils are successively fed from the bottom of a stack to an addressing or-printing machine, the same comprising a hopper, a reciprocatory pusher maintained' to engage with the lowermost card or stencil of the stack, and a follower which normally rests upon the stack and serves to lock the reciprocatory pusher member against movement when in line therewith.

3. In a device of the character set forth, means for maintaining a stack of stencils or the like, comprising vertical supports which bridge a way for stencils, a weighted follower which in use rests upon the stack of stencils, a reciprocatory pusher movablein line with the lower stencil of the stack, effective to project a single stencil beyond the aforesaid follower, said follower being of such construction as to intercept the path of the pusher and prevent movement thereof when the last stencil has been projected.

In testimony whereof I have signed my name to this specification.
